SPECIFICATION forming part of Letters Patent No. 639,353, dated December 19, 1899.

Application filedMarch 6,1899. Serial No. 707,884. (Nomodel-l T0 to whom it may concern:

Be it known that I, GEORGE V. BUGIBEE, a citizen of the United States, residing at Delhi, in the county of Hamilton and State of Ohio, have invented certain new and. useful Improvements in Planing and Matching Machines, of which the following is a specification.

My invention relates particularly to that class of planing and matching machines adapted to plane or match the edges of comparatively thin stock, such as is used in boxes, picture -backing, for making gluejoints, and for similar purposes.

My invention consists in'providing a maously-advancing feeding-faces, and in the various parts and in the arrangement and com binations of parts hereinafter more fully described and claimed. y

In the drawings, Figure 1 represents a front elevation of my improved device. Fig. 2 isa plan View of the same with one pair of the feedingchains omitted, and Fig. 3 is a side elevation of the same. Fig. 4: is a plan and end view of a part of the chain and. its guiding-plate; and Fig. 5 represents a side elevation, front, and bottom View of one of the chain-links.

A represents the frame of the machine, supporting brackets B Bf, carrying mandrels b b, moun ted,preferably,at each end in bearings 19 I). The brackets slide in ways aonthe frame of the machine and are adjusted by means of bolts a a rotatably secured against endwise movement in lugs a cfiand takinginto threaded projections b b on the brackets. The man-v drels carry suitable cutter-heads O C, removabl y secured thereto, and suitable pulleys for operating the same. The cutter-heads O O are adapted to carry oppositely-arranged cutting agencies forcutting the meeting faces The cutter-heads operate, respectively,in a plane between each of the pair of feeding-chains hereinafter mentioned, which latter feed the hoards over the cutter-heads.

and carrying the sprocket-wheels all.

The material is fed through the machine between feeding-chains D D, consisting of a series of links 01, having feeding-faces d, with hooks d at one end taking aboutstems d at the other end of the next succeeding link and arranged to slip about the stem through a recess d in the link. The feedingfaces are preferably integral with the chainlinks, which latter I prefer to construct in a single piece with their mutually-connecting parts in such manner as to be releasably connected, thus reducing the number of points of wear in the chain to the minimum, allowing any link to be readily removed, and pro ducing a chain substantial in structure and efficient in operation. The chains D may take about sprocket-wheels d d and the chains D take about sprocket-wheels 61" (1 E is a shaft having pulleys e c to receive power from any suitable source and carrying a suitable pinion c, meshing with a gearf on a shaft F. The shaft carries bevel-pinionsf,

rigidly secured thereto, meshing with bevelgears f on a shaft f journaled in the frame The shaft F also has splined thereto bevel-gears .f, meshing with bevel-gearsy, mounted on a shaft f journaled in a slide G and carrying the sprocket-wheel d The slide G is adjustable in ways a by means of a screw-shaft g, carrying a handwheel 9. r The screw-shaft is tapped into a suitable lug on the slide Gand passes loosely through a cap 9 A spring g is preferably interposed between the lug on the slide and the cap and yieldingly holds the slide and its attendant parts up to their work. The slide has a bearin g g for a pivot g for a bracket H. A stud-h takes into a slot h in the bracket and is adjusted therein by a bolt W and secured in place by a nut 77.3. The sprocketwheel (1 may be mounted on the stud. The bracket contains an opening its to allow for the removal and adjustment ofthe cutter-head without interference with, obstruction by, or adjustment of any other part of the machine. The bracket also carries an extension h at, preferably, right an glcs to its length, through which a bolt h is adapted to pass into the slide, a spring h being employed to force the swinging end of the bracket toward the stock to be operated. The bolt 7L carries an idlerroll h", movable in a slot a in an ear a bolted to the frame of the machine. also carries a pendant H taking into an annular groovef in the hub of the bevel-gearf.

I I are brackets secured to the frame of the machine, carrying bearings t' for the shaftsf the shafts preferably having one of the bearin gs at each end. The sprocket-wheels d are securedto the shafts f. The brackets I also carry studs F, on which the sprocket-wheels (i may rotate. Bolts i take through the bracket and into the studs 1", adjusting the latter in the slots 2, wherein they may also be secured by means of nuts 6'. By means of the adjustment of the studs h and i proper tension is given to the feeding-chains. A setscrew 2' is tapped into a lug a and has a locknut i The set-screw i takes against the free end of the bracketI and gives it adjustmentand rigidity. The brackets H and I also preferably have guiding-plates K for the feeding-chains, secured thereto, preferably, by

means of bolts 70, taking through slots 70 intothe brackets. The guiding-plates carry suitable guides 70 k for grooves d (Z in the links.

L L are tables earryinggagesll, which may be secured thereto by means of bolts 1*, taking through the slots Z into the table. bles are also preferably secured to slides M M, sliding in brackets a adjustable by means ofset-screws m and secured by means of setbolts m,-t'aking through slots in the brackets into the slides. The connection and adjustment between the slides and tables is preferably'secured by means of set-bolts Z 1 taking through slots Z Z in the table, and by means or set-screws Z Z", tapped into lugs Z I, which may take against the lower edge of the table, giving it a pivotal adjustment.

In operation the stock to be operated upon is placed on a'work-support Nand thence fed into the machine. The work-support is placed conveniently between the two pairs of feedingattend to both.

chains in such position that one operator may The chain D serves as the fixed face or gage to determine the line of cut. The gages H are set to correspond to the chain D. The tables may be set angling slightly upward toward the rear by means of the set screws Z Z", thus giving lead to the stock. If it be desirous to make a hollowing cut, the feeding-in table is set with its free'end drooping and the feeding-out table may be' The bracket I-I The ta yieldingly on the stock when it enters be-' tween the feed devices and, with the spring 9 increases the pressure as the stock advances. This construction insures the immediate positive gripping of the stock as soon as it comes in contact with the chains and the positive feeding of the material through the machine. As the stock advances toward the rear end of-the chains the tension on the spring h increases, and when the tension of the spring 71 is increased sufficiently to overcome the normal tension ofthe spring g or is exhausted the latter spring is brought into play by the slide G giving against the tension of the latter spring and the stock is held between the feeding-faces by the combined action of the springs 72/8 and 9 It is desirable in presenting stock to be fed that the yield of the feeding-faces where they take hold of the stock shall be slight and the feeding-facescomp'aratively easily separated, but that'the hold of the feeding-faces on the stock at the point where the cutter-head makes contact with the stock shall be firm and rigid to resist the thrust of the cutter-head against the stock and maintain the latter in its proper relation to the cutter-head. I attain these objects by simple and effective devices. The stock is grasped by moving feeding-faces from-both sides at the same time, which carry it through the inachine at a rapid rate of feed, the stock being relatively stationary to both its impacting feeding-faces while passing through the machine. The feeding-faces also form a substantially continuous moving feeding agency on both sides of the stock, enabling extremely short pieces of,"say,two to four inchesin length to be fed through the machine at a'r'apid rate of feed.

In my device the stock is fed th'roug hthe machine on edge between twojsubstantially continuous plane feeding-faces moving in unison above the acting cutter-head, operating in a vertical plane between the'same in suchway that one of the feeding-faces may serve as the gage or determine the line of travel of the stock and the line of cut on the same and the other yield pivotallyand bodily for the purposes stated and to variations in thickness of stock and hold thestock firmly between the feeding-faces, which latter present substantiallycontinuous plane feedingsurfaees to both sides of the stock, with the stock moving relatively stationary to the latter between the same while it is being fed through the machine,with plane feeding-faces contacting against both its sides in a substantially continuous line,and with guiding-plates for the feeding-faces maintaining the'faees the faces in unison, a rigid support for one of the series of faces, a yielding support for the other, and a guiding-plate for each series of flexible faces, with means for the adjustment of the guiding-plate laterally on its support in a plane at substantially right angles to the axes of the wheels, and means for securing the guiding-plates rigidly with relation to their respective supports after adj ustment, substantially as described.
